About this program
The Department of the Interior's Bureau of Reclamation is funding aquatic ecosystem restoration projects through grants and cooperative agreements under CFDA 15.580 (WaterSMART Aquatic Ecosystem Restoration), with the most recent award disbursed October 28, 2025.
The program funds study, design, and construction of collaboratively developed aquatic ecosystem restoration projects that improve fisheries, wildlife, and aquatic habitat health or restore fish passage. Representative recent awards include the Yurok Tribe's one-mile restoration of Weaver Creek for ESA-listed coho salmon habitat in California ($4.6 million); the Nambe Reservoir restoration planning project in New Mexico addressing dissolved oxygen and wildfire impacts ($1.03 million); the Pueblo of San Felipe's comprehensive bosque and riverine restoration plan ($411 thousand); and the California Department of Water Resources' Colusa Basin restoration design study targeting Central Valley chinook salmon spawning habitat ($4.08 million). Projects emphasize floodplain reconnection, fish passage barrier removal, habitat complexity creation, riparian restoration, and water quality improvements in river systems affected by dams, diversions, agricultural development, and climate impacts.
The portfolio shows strong recent momentum: 27 awards totaling $61.2 million in federal dollars obligated since March 2023, with awards accelerating from 1 in 2023 to 11 in 2024 to 15 in 2025. Reclamation is the sole funding agency. The assistance-type mix is predominantly Project Grants (23 awards, 85 percent) with a smaller share of Cooperative Agreements (4 awards, 15 percent). Award magnitudes range from roughly $411 thousand to $11.6 million, with typical design-phase projects in the $1 million to $4 million range and construction projects reaching toward the higher end.
A competitive merit-based funding opportunity (R25AS00029) was posted December 10, 2024, with due date January 31, 2025, soliciting projects for fiscal years 2025 and 2026. However, the solicitation is currently paused and under review; Reclamation advises checking the WaterSMART website for updated schedule information and application deadlines. The prior funding opportunity (R23AS00106) for fiscal years 2023 and 2024 closed February 16, 2024. Merit review prioritizes projects with diverse stakeholder support (agricultural, hydroelectric, potable water, industrial water, tribal, commercial fishing, and conservation representatives), multi-basin or regional scope, and contributions to ESA-listed anadromous fish recovery. Environmental and cultural resource compliance is required before project commencement.

The Aquatic Ecosystems Restoration Program provides cost-shared financial assistance for the study, design and construction of aquatic ecosystem restoration projects that are collaboratively developed, have widespread regional benefits, and result in the improvement of the health of fisheries, wildlife, and aquatic habitat through restoration and improved fish passage.
